"We believe this is a safe aircraft," he said during a Friday morning press conference.

The FAA conference came hours after two more Boeing 787 Dreamliners faced problems.

An All Nippon Airways aircraft suffered a crack to its windscreen during a flight in Japan and an oil leak was found coming from the engine of a separate plane after it landed at an airport in southern Japan, Reuters reporting.

In the first incident, according to Reuters, a crack was discovered in the window area in front of the pilot's seat an hour into the flight. The plane landed safely at an airport in Western Japan.

The oil leak found in the second 787 Dreamliner was discovered after that aircraft landed at Miyazaki airport, in the south, Reuters reports.

Boeing has delivered 50 of the new planes and another 800 are on order. Huerta said the review would focus on electronics. He said the review would be "expeditious," but couldn't say how long it would take, Jansen reports.

Said Transportation Secretary Ray LaHood: "We are concerned about recent events involving Boeing 787. We will look for root causes of recent events and do everything possible to make sure they don't happen again. We are going to work very hard to get to the bottom of this."

Boeing President Ray Conner, who participated in the press conference, said the Dreamliner went through a rigorous certification process. "We have complete confidence in the 787, and so do our customers," he said.

Boeing -- which began rolling out the new plane in late 2011 -- said it is cooperating with the administration on the review.

There have been five incidents involving problems with the Dreamliner this week, including two in the USA.
